1、UIImage+RenderMode.h
#import <UIKit/UIKit.h>
@interface UIImage (RenderMode)
/** 取消UIImage的渲染模式 */
+ (UIImage *)imageRenderingModeImageNamed:(NSString *)imageName;
@end
#import "UIImage+RenderMode.h"
@implementation UIImage (RenderMode)
+ (UIImage *)imageRenderingModeImageNamed:(NSString *)imageName
{
UIImage *image = [UIImage imageNamed:imageName];
return [image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
}
@end
2、UIColor+Hex.h
#import <UIKit/UIKit.h>
@interface UIColor (Hex)
/** 默认alpha为1 */
+ (UIColor *)colorWithRed:(CGFloat)red green:(CGFloat)green blue:(CGFloat)blue;
/** 从十六进制字符串获取颜色,默认alpha为1 */
+ (UIColor *)colorWithHexString:(NSString *)color;
/** 从十六进制字符串获取颜色，alpha需要自己传递 color:支持@“#123456”、 @“0X123456”、 @“123456”三种格式 */
+ (UIColor *)colorWithHexString:(NSString *)color alpha:(CGFloat)alpha;
@end
#import "UIColor+Hex.h"
@implementation UIColor (Hex)
+ (UIColor *)colorWithRed:(CGFloat)red green:(CGFloat)green blue:(CGFloat)blue{
return [UIColor colorWithRed:red green:green blue:blue alpha:1];
}
+ (UIColor *)colorWithHexString:(NSString *)color alpha:(CGFloat)alpha
{
//删除字符串中的空格
NSString *cString = [[color stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] uppercaseString];
// String should be 6 or 8 characters
if ([cString length] < 6)
{
return [UIColor clearColor];
}
// strip 0X if it appears
//如果是0x开头的，那么截取字符串，字符串从索引为2的位置开始，一直到末尾
if ([cString hasPrefix:@"0X"])
{
cString = [cString substringFromIndex:2];
}
//如果是#开头的，那么截取字符串，字符串从索引为1的位置开始，一直到末尾
if ([cString hasPrefix:@"#"])
{
cString = [cString substringFromIndex:1];
}
if ([cString length] != 6)
{
return [UIColor clearColor];
}
// Separate into r, g, b substrings
NSRange range;
range.location = 0;
range.length = 2;
//r 截取的range = (0,2)
NSString *rString = [cString substringWithRange:range];
//g
range.location = 2;// 截取的range = (2,2)
NSString *gString = [cString substringWithRange:range];
//b
range.location = 4;// 截取的range = (4,2)
NSString *bString = [cString substringWithRange:range];
// Scan values
unsigned int r, g, b;//将字符串十六进制两位数字转为十进制整数
[[NSScanner scannerWithString:rString] scanHexInt:&r];
[[NSScanner scannerWithString:gString] scanHexInt:&g];
[[NSScanner scannerWithString:bString] scanHexInt:&b];
return [UIColor colorWithRed:((float)r / 255.0f) green:((float)g / 255.0f) blue:((float)b / 255.0f) alpha:alpha];
}
//默认alpha值为1
+ (UIColor *)colorWithHexString:(NSString *)color
{
return [self colorWithHexString:color alpha:1.0f];
}
@end
3、UIView+AdjustFrame.h（补充：Adjust是"调整"的意思）
#import <UIKit/UIKit.h>
@interface UIView (AdjustFrame)
//类别可以拓展属性，但是不能生成set和get方法
@property (assign, nonatomic) CGFloat adjust_x;
@property (assign, nonatomic) CGFloat adjust_y;
@property (assign, nonatomic) CGFloat adjust_width;
@property (assign, nonatomic) CGFloat adjust_height;
@property (assign, nonatomic) CGSize adjust_size;
@property (assign, nonatomic) CGPoint adjust_origin;
@end
#import "UIView+AdjustFrame.h"
@implementation UIView (AdjustFrame)
#pragma mark - adjust_x
-(void)setAdjust_x:(CGFloat)adjust_x{
CGRect frame = self.frame;
frame.origin.x = adjust_x;
self.frame = frame;
}
-(CGFloat)adjust_x{
return self.frame.origin.x;
}
#pragma mark - adjust_y
-(void)setAdjust_y:(CGFloat)adjust_y{
CGRect frame = self.frame;
frame.origin.y = adjust_y;
self.frame = frame;
}
- (CGFloat)adjust_y
{
return self.frame.origin.y;
}
#pragma mark - adjust_width
-(void)setAdjust_width:(CGFloat)adjust_width{
CGRect frame = self.frame;
frame.size.width = adjust_width;
self.frame = frame;
}
- (CGFloat)adjust_width
{
return self.frame.size.width;
}
#pragma mark - adjust_height
-(void)setAdjust_height:(CGFloat)adjust_height{
CGRect frame = self.frame;
frame.size.height = adjust_height;
self.frame = frame;
}
- (CGFloat)adjust_height
{
return self.frame.size.height;
}
#pragma mark - adjust_size
-(void)setAdjust_size:(CGSize)adjust_size{
CGRect frame = self.frame;
frame.size = adjust_size;
self.frame = frame;
}
- (CGSize)adjust_size
{
return self.frame.size;
}
#pragma mark - adjust_origin
-(void)setAdjust_origin:(CGPoint)adjust_origin{
CGRect frame = self.frame;
frame.origin = adjust_origin;
self.frame = frame;
}
- (CGPoint)adjust_origin
{
return self.frame.origin;
}
@end
4、关于处理颜色比较好的工具类，功能：NSCache缓存处理颜色对象提高性能、十六进制颜色值处理（包含了UIColor+Hex.h的功能）等等
#import <UIKit/UIKit.h>
@interface UIColor (Hex)
/** 默认alpha为1 */
+ (UIColor *)colorWithRed:(CGFloat)red green:(CGFloat)green blue:(CGFloat)blue;
/** 从十六进制字符串获取颜色,默认alpha为1 */
+ (UIColor *)colorWithHexString:(NSString *)color;
/** 从十六进制字符串获取颜色，alpha需要自己传递 color:支持@“#123456”、 @“0X123456”、 @“123456”三种格式 */
+ (UIColor *)colorWithHexString:(NSString *)color alpha:(CGFloat)alpha;
@end
#import "UIColor+Hex.h"
@implementation UIColor (Hex)
+ (UIColor *)colorWithRed:(CGFloat)red green:(CGFloat)green blue:(CGFloat)blue{
return [UIColor colorWithRed:red green:green blue:blue alpha:1];
}
+ (UIColor *)colorWithHexString:(NSString *)color alpha:(CGFloat)alpha
{
//删除字符串中的空格
NSString *cString = [[color stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] uppercaseString];
// String should be 6 or 8 characters
if ([cString length] < 6)
{
return [UIColor clearColor];
}
// strip 0X if it appears
//如果是0x开头的，那么截取字符串，字符串从索引为2的位置开始，一直到末尾
if ([cString hasPrefix:@"0X"])
{
cString = [cString substringFromIndex:2];
}
//如果是#开头的，那么截取字符串，字符串从索引为1的位置开始，一直到末尾
if ([cString hasPrefix:@"#"])
{
cString = [cString substringFromIndex:1];
}
if ([cString length] != 6)
{
return [UIColor clearColor];
}
// Separate into r, g, b substrings
NSRange range;
range.location = 0;
range.length = 2;
//r 截取的range = (0,2)
NSString *rString = [cString substringWithRange:range];
//g
range.location = 2;// 截取的range = (2,2)
NSString *gString = [cString substringWithRange:range];
//b
range.location = 4;// 截取的range = (4,2)
NSString *bString = [cString substringWithRange:range];
// Scan values
unsigned int r, g, b;//将字符串十六进制两位数字转为十进制整数
[[NSScanner scannerWithString:rString] scanHexInt:&r];
[[NSScanner scannerWithString:gString] scanHexInt:&g];
[[NSScanner scannerWithString:bString] scanHexInt:&b];
return [UIColor colorWithRed:((float)r / 255.0f) green:((float)g / 255.0f) blue:((float)b / 255.0f) alpha:alpha];
}
//默认alpha值为1
+ (UIColor *)colorWithHexString:(NSString *)color
{
return [self colorWithHexString:color alpha:1.0f];
}
@end
5、NSTimer+Addition 关于计时器的类别工具
#import <Foundation/Foundation.h>
@interface NSTimer (Addition)
- (void)pauseTimer;
- (void)resumeTimer;
- (void)resumeTimerAfterTimeInterval:(NSTimeInterval)interval;
@end
#import "NSTimer+Addition.h"
@implementation NSTimer (Addition)
-(void)pauseTimer
{
if (![self isValid]) {
return ;
}
[self setFireDate:[NSDate distantFuture]];
}
-(void)resumeTimer
{
if (![self isValid]) {
return ;
}
[self setFireDate:[NSDate date]];
}
- (void)resumeTimerAfterTimeInterval:(NSTimeInterval)interval
{
if (![self isValid]) {
return ;
}
[self setFireDate:[NSDate dateWithTimeIntervalSinceNow:interval]];
}
@end
6、给任意的UIView添加点击事件
#import <UIKit/UIKit.h>
@interface UIView (AddClickedEvent)
- (void)addClickedBlock:(void(^)(id obj))tapAction;
@end
#import "UIView+AddClickedEvent.h"
#import <objc/message.h>
@interface UIView ()
@property void(^clickedAction)(id);
@end
@implementation UIView (AddClickedEvent)
- (void)setClickedAction:(void (^)(id))clickedAction{
objc_setAssociatedObject(self, @"AddClickedEvent", clickedAction, OBJC_ASSOCIATION_COPY_NONATOMIC);
}
- (void (^)(id))clickedAction{
return objc_getAssociatedObject(self, @"AddClickedEvent");
}
- (void)addClickedBlock:(void(^)(id obj))clickedAction{
self.clickedAction = clickedAction;
// hy:先判断当前是否有交互事件，如果没有的话。。。所有gesture的交互事件都会被添加进gestureRecognizers中
if (![self gestureRecognizers]) {
self.userInteractionEnabled = YES;
// hy:添加单击事件
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tap)];
[self addGestureRecognizer:tap];
}
}
- (void)tap{
if (self.clickedAction) {
self.clickedAction(self);
}
}
@end
